Full Transcript

Chad shows how to use Hess's Law to calculate the Delta H of a reaction. He begins by showing how to manipulate chemical equations and the effect on the Delta H value. He then works 2 Hess's Law sample problems. In the 2nd example, he also explains the shortcut to arriving at the correct answer before going back and working it out the long way as well.
